Cops raided the home of Karim Cheurfi, who is said to have a previous conviction for shooting at police

Was it a terror attack?

ISIS claimed responsibility for the attack as police said they knew the identity of the suspect, believed to be 39-year-old Karim Cheurfi.

President Francois Hollande had said officials were “convinced” the incident was a terror attack, even before ISIS claimed responsibility and the Paris Prosecutor’s anti-terror office opened an inquiry.

Cheurfi was previously jailed for 20 years for shooting at cops in 2001 but was released early, according to reports.

He is also thought to have been known to security services for “extremist links” and is believed to have been questioned recently in Meaux, outside Paris, after “informants” told cops he was “seeking to obtain weapons to kill policemen.”

Isis mouthpiece Amaq said the killer is known as al-Belgiki – the Belgian.

On the morning of April 21 a Belgian man French cops said they were also hunting in connection with the attack handed himself into a police station in Antwerp.

The 35-year-old had been described as “very dangerous” and was reported to be in possession of firearms and a train ticket from France, Le Parisien reported.

In the hours following the attack officers raided a house in the eastern Paris suburb Chelles – the family home of Cheurfi, reportedly finding guns and ammunition.
